Abstract

The invention discloses a pipeline leakage detection device and detection method. The device comprises a wrapping body (1) which coats a detected pipeline segment (100) and forms annular sealing; the wrapping body (1) extends along the axis of the detected pipeline segment (100), and a space (2) for containing gas is reserved between the inner wall face of the wrapping body (1) and the outer wall of the detected pipeline segment (100); the two ends of the wrapping body (1) are provided with through holes (3) for containing the detected pipeline segment (100); a gas leakage induction device (4) for monitoring whether leakage is generated to the detected pipeline segment (100) or not is arranged on the wrapping body (1); and the gas leakage induction device (4) is electrically connected with an external controller. After the structure is adopted, the pipeline leakage detection device which can carry out gas leakage detection and alarming and discharge leaked gas to a designated place and meanwhile achieves whole-process monitoring of a pipeline connector, a weld joint and a whole pipeline is provided.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a pipeline leakage detection device and detection method. Background technique [0002] The usual pipeline or system airtight inspection is generally to check the airtightness of the welding or joint parts of the pipeline or system in the non-working state. Leakage method, differential pressure method, vacuum method, etc. However, the high-pressure pipeline in the working state is always in the state of replenishing air, and a small amount of leakage cannot be reflected by a small change in pressure. Therefore, none of the above methods is suitable for leakage monitoring of high-pressure pipelines in working conditions. [0003] Monitoring the leakage of the gas pipeline in the working state can be realized by using a gas leakage sensor according to the gas type. For example, a certain number of oxygen concentration sensors can be installed near the pipeline that may...
